Heading east from Thief Lake WMA I decided to check out Norris Camp, a remote Minnesota DNR station in the Beltrami Island State Forest that I’d heard had a nesting Black-backed Woodpecker. I was pretty sure that I was too late as most woodpeckers had fledged young already. But I was in luck! And I spent a couple hours with this pair of rarely seen boreal woodpeckers.

The folks at the camp pointed out that this was the same mated pair that nested on the grounds last summer. How did they know? Notice the band on the adult’s leg; they actually banded them last year and both the male and female returned to nest only 100 yards from last year’s nest. Woodpeckers NEVER use the same cavity twice but always excavate a new nest; it may be in the same tree but usually not. In this case, the tree they used last year had blown down since last summer. I don’t know much about site fidelity or mate fidelity in woodpeckers but this was a very interesting anecdote that I will for follow up on.
Also note the male’s yellow cap; the female shows only black on the head. He’s feeding a young male who is already sporting his jaunty yellow forehead feathers.

Macoun’s Arctic (Oenis macounii) at Norris Camp, Beltrami Island State Forest, Lake of the Woods County, Minnesota.
While waiting and watching at the Black-backed Woodpecker nest, I was treated to a lifer butterfly. Not 20 feet away I noticed an orange butterfly that was repeatedly landing on the same fallen log. I finally took a closer look and lo and behold, a Macoun’s Arctic! This species only flies every other year in the North Woods so I just happened to be in the right place at the right time. They are found in openings in sandy Jack Pine forests, and that is exactly the habitat I was in. Males use the same perch as they wait for females.

Macoun’s Arctic (Oenis macounii) at Norris Camp, Beltrami Island State Forest, Lake of the Woods County, Minnesota.
When perched with wings folded, the Macoun’s Arctic is well camouflaged, like just another piece of bark. This species has a fairly limited range in North America extending from the North Shore of Lake Superior west and north to Churchill, Manitoba, British Columbia and just extending north into the Northwest Territories.

Ram’s-head Ladyslipper (Cypripedium arietinum) near Norris Camp in Beltrami Island State Forest, Lake of the Woods County, Minnesota.
One of my favorite orchids found in the bogs of north central Minnesota, the Ram’s-head Ladyslipper. This small group was past prime as you can tell by the collapsed dorsal sepal on top of the slipper pouch. This may mean that the flower had already been pollinated. It is a very small ladyslipper, maybe 6 inches tall. This group was growing in a Cedar bog.

My last stop was Big Bog State Recreation Area (SRA) near Waskish, Minnesota on Red Lake. This is the largest patterned peatland in the lower 48, and massive in size. It was once home to Minnesota’s last wild Caribou herd which disappeared in the 1930s and 40s. Their trails can still be seen from the air.
The boardwalks is one mile long and a very pleasant hike. MANY interpretive signs highlight the human and natural history of the Big Bog.

Bog Fritillary (Boloria eunomia) on the Big Bog SRA boardwalk.
This was my lifer Bog Fritillary! Unfortunately I mistook it for a different, more common species, and I didn’t take the time to get a really good photo. Oh well, just a reason to go back!
I was going to camp overnight in the area, but I got a text message on my phone that a Calliope Hummingbird had shown up in Duluth…in breeding plumage! This is a bird of the mountain west that has only been recorded in Minnesota a couple times…and never in its stunning breeding plumage. This was reason enough to head for home.
